      Text en actes de congrés
      Accés obert
      This paper presents a comprehensive analysis of SVPWM for a five-phase VSI based on SiC devices applied to motor drives. The modulation techniques analyzed use medium and large vectors to reach the reference vector. The ...

    • Study of modulation techniques applied to full bridge single-phase inverters based on wide-bandgap semiconductors 

      Ferrer Arnau, Luis Jorge; Berbel Artal, Néstor; Capellá Frau, Gabriel José; Zaragoza Bertomeu, Jordi (2019)
      Comunicació de congrés
      Accés obert
      Wide-band gap (WBG) devices are gradually replacing standard Si semiconductors in power converters. This is due to the fact that WBG devices exhibit lower capacitance and on-resistance and besides, as they can switch at ...

    • Efficiency analysis of wide band-gap semiconductors for two-level and three-level power converters 

      Lumbreras Carrasco, David; Zaragoza Bertomeu, Jordi; Mon González, Juan; Gálvez, Eduardo; Collado Escolano, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Comunicació de congrés
      Accés obert
      Power devices based on wide band-gap materials are emerging as alternatives to silicon-based devices. These new devices allow designing and building converters with fewer power losses, and are thus more highly efficient ...

    • Submodule power losses balancing algorithms for the modular multilevel converter 

      Picas Prat, Ricard; Pou, Josep; Zaragoza Bertomeu, Jordi; Watson, Alan; Konstantinou, Georgios; Ceballos Recio, Salvador; Clare, John (Institute of Electrical and Electronics Engineers (IEEE), 2016)
